2005 ML500 High Beams won't come on
Hello,
Can someone guide me on where to start trouble shooting? Is there a relay or voltage I can check at certain places?
Not sure if there is a module at fault or wiring or relay.
Thanks.

Do you have a scanner to read codes in the EAM and Headlamp Range control modules.

Do you have a wiring diagram for the high beam headlight circuit? Or know where I can access?

Agreed, assuming one is aware of the existence of said scanner. Some of us aren't born with this knowledge.

Good day to you.

Hi,
I have to replace the brake pads on my ML500. Can you comment on the ceramic pads you have? I was thinking to upgrade to semi-metalic because I like a touchy brake grab. However the stock european style of initial grab is already pretty good. What do you think?
Thanks.
Joe
